Accompanying drawing explanation
Fig. 1 is for the flow chart of operation of manufacture method of the metal material of the repressed shaping described in embodiments of the present invention is described.
The specific embodiment
Below, the embodiment to the manufacture method of member for the manufacture method of the metal material of repressed shaping of the present invention and heat exchanger (following, suitable be called manufacture method of the present invention), is described in detail.
First, the metal material using in manufacture method of the present invention and graphite powder are described.
< metal material >
Metal material for using in manufacture method of the present invention, is not particularly limited, and can be the metal material of any kind.But, manufacture method of the present invention is owing to having the good such feature of press formability of performance, so in the situation that using in metal material poor pure titanium, titanium alloy or the stainless steel etc. of press formability particularly as object, bring into play significant effect of the present invention.
In addition, the shape of metal material be so long as can carry out compressing shape and be just not particularly limited, and such as being tabular etc., in compressing postforming, is various desired shapes.
Wherein, metal material is not limited to specific pure titanium, titanium alloy or the stainless steel forming, but while using the material being formed by pure titanium, titanium alloy, viewpoint from the cold rolling easiness of titanium material (mother metal) (without intermediate annealing and can to implement total reduction be more than 35% cold rolling), be preferably O:1500ppm following (more preferably 1000ppm is following), Fe:1500ppm following (more preferably 1000ppm is following), C:800ppm is following, N:300ppm is following, below H:130ppm, remainder by Ti and inevitably impurity form.For example can use the cold-reduced sheet of JIS1 kind.
< graphite >
The graphite using in manufacture method of the present invention in flaky graphite powder, flaky graphite powder, expansion fossil ink powder and thermal decomposition graphite powder any or take the graphite powder that they are main body.
Conventionally, graphite powder is roughly divided into graphous graphite powder and natural graphite powder.Wherein, graphous graphite powder is the powder that made graphite electrode pulverizing is obtained, and on the other hand, natural graphite powder is that the powder of the rotten mineral that generate occurs biology/plant etc. by being subject to underground heat or ground pressure.And, in the classification of this natural graphite powder, comprise flaky graphite powder (also referred to as blocky graphite powder), flaky graphite powder, soil graphite powder.
In addition,, except the graphite powder of mentioned kind, as graphite powder, also there is expanded graphite powder, expansion fossil ink powder, thermal decomposition graphite powder.Wherein, expanded graphite powder is to insert after compound at the interlayer of flaky graphite powder by flaky graphite powder is carried out to chemical treatment, the graphite powder that makes this compound gasification that graphite is obtained according to the mode sex change of expanding by heat treatment.In addition, expansion fossil ink powder is to make to pulverize the graphite powder obtaining after its expansionization by expanded graphite powder further being implemented to heat treatment.In addition, thermal decomposition graphite powder is powder coke is heat-treated at approximately 3000 ℃ and after graphitization, to pulverize the graphite powder obtain.
Inventors conduct in-depth research various types of graphite powder, found that, in above-mentioned graphite powder, when flaky graphite powder, flaky graphite powder, expansion fossil ink powder, thermal decomposition graphite powder are used for to the formation of graphite linings, can on whole of metal material, form fine and close graphite linings.
On the other hand, graphous graphite powder is owing to being stone material, thus even if exert pressure and be also difficult to crush, consequently, graphous graphite powder only become metal material surface with granular joint the state on whole of coated metal surface not.Under such state, when compressing operation, become the occurrence cause with the sintering of mould, can not get good press formability.Therefore, preferably graphous graphite powder is not used for to manufacture method of the present invention.
On the other hand, natural graphite powder is generally used as the core of pencil or propelling pencil (mechanical pencil), additive in lubricating fluid.And in natural graphite powder, the grain of flaky graphite powder, flaky graphite powder, expansion fossil ink powder, its powder of thermal decomposition graphite powder becomes the form of squamous, and this is formed by the thin slice accumulation of thinner graphite self.If such graphite powder is applied to and implements after metal material surface compressingly, the thin slice that forms the grain of powder is slided and is launched by pressure each other, thus the surface of covering metal material.Therefore,, if use flaky graphite powder, flaky graphite powder, expansion fossil ink powder, thermal decomposition graphite powder, can form the graphite linings of whole of coated metal material.
In addition, in these graphite powders, the fossil ink powder that particularly expands, owing to there being fine space between thin slice, so easily crush when being under pressure, more easily launches by causing the slip between thin slice.Thereby, particularly preferably use expansion fossil ink powder.
In addition, if use flaky graphite powder, flaky graphite powder, expansion fossil ink powder, thermal decomposition graphite powder, due to the reduction ratio with low, also can form the fine and close graphite linings with lubricity with high coating rate, so probability of happening of the defective in the time of can reducing compressing operation, consequently, productivity ratio is excellent, and aspect cost, advantage is also large.
According to above content, even if use flaky graphite powder, flaky graphite powder, expansion fossil ink powder, the thermal decomposition graphite powder that is also difficult to the soil graphite powder that crushes etc. in native graphite except exerting pressure in the present invention.
The graphite using in manufacture method of the present invention can only be used any one in flaky graphite powder, flaky graphite powder, expansion fossil ink powder, thermal decomposition graphite powder, also they suitably can be mixed and uses.In addition can be also to take the graphite powder that they are main body.The graphite powder that the mode of the mixed-powder that should " take them be main body graphite powder " preferably comprises any one or they in more than 50 quality % flaky graphite powder, flaky graphite powder, expansion fossil ink powder, thermal decomposition graphite powder according to the gross mass of the graphite powder with respect to being used is adjusted.This be due to, if the ratio of any one in flaky graphite powder, flaky graphite powder, expansion fossil ink powder, thermal decomposition graphite powder or their mixed-powder is lower than 50 quality %, when compressing operation whole of metal material not by graphite linings coating, likely press formability is deteriorated.
More preferably use the situation of the graphite powder that the mixed-powder of any one or they in flaky graphite powder, flaky graphite powder, expansion fossil ink powder, thermal decomposition graphite forms.
The particle diameter of graphite powder is preferably 0.02～100 μ m.This be due to, if particle diameter lower than 0.02 μ m when the compressing operation graphite powder be difficult to crush and the possibility of whole that cannot coated metal material is high, if particle diameter surpasses the compressing easy variation of precision of 100 μ m.
The graphite linings that during then, to the compressing operation of manufacture method of the present invention, when compressing operation (or during crimping process and) forms describes.
< graphite linings >
Graphite linings is that when compressing operation (or during crimping process and) is formed at the surperficial layer of metal material when compressing operation, and utilizes above-mentioned graphite powder to form.
The adhesion amount of graphite linings is not particularly limited, but is preferably 10～1000 μ g/cm
2.This be due to, lower than 10 μ g/cm
2time, cannot covering metal material when compressing operation because quantity of graphite is few whole, so become that the mould using in compressing operation directly contacts with the surface of metal material and reason that sintering occurs.On the other hand, this be due to, if surpass 1000 μ g/cm
2the such effect of the raising of press formability is saturated.
In addition, this graphite linings is removed in operation and is removed at graphite.
